Ombré hair colour has been hot for a while now, and so has the bright, colourful streak trend. So, why not combine the two together like Ke$ha’s vivid turquoise streak cascading down into a dark navy blue. Kate Bosworth opted for the dip-dye technique, instead of individual sections of hair coloured blue. And LC (Lauren Conrad) recently debuted some very colourful rainbow streaks. But it appears the color has faded out – now LC was seen with barely blue strands in her luscious locks. Would you jump on this blue streak trend?
